Grammar Rule in 30 Seconds

These three characters function as formal, literary versions of common prepositions to elevate your academic and professional Chinese.

  • 以 (yǐ) functions like 'using' or 'by means of' (e.g., 以此为准).
  • 于 (yú) replaces 在 (zài) or 向 (xiàng) in formal contexts (e.g., 处于困境).
  • 与 (yǔ) acts as 'and' or 'with' in formal lists or comparisons (e.g., 与此同时).
Formal Context + [以/于/与] + Noun/Verb Phrase

Overview

Transitioning to the C1 level in Chinese necessitates a command of register—the ability to shift between informal spoken language and sophisticated written language (书面语 | shūmiànyǔ). The coverbs 用 (yòng), 在 (zài), and 和 (hé) are the workhorses of daily conversation, but in formal discourse they can appear elementary. To achieve true professional and academic proficiency, you must integrate their classical, formal counterparts: 以 (yǐ), 于 (yú), and 与 (yǔ).

These three characters are not simple one-to-one replacements. They are pillars of literary Chinese, carrying centuries of grammatical history. Their usage imparts a sense of precision, elegance, and authority.

Mastering them involves understanding a more condensed and structured syntax inherited from Classical Chinese. 以 functions as a tool of instrumentality and basis; 于 as a marker of abstract location in time, space, or relation; and 与 as a connector of parallel elements. This guide provides a comprehensive breakdown of their functions, structures, and the linguistic logic that governs their use, equipping you to use them with confidence.

How This Grammar Works

A coverb (or preposition) works with a noun phrase to create an adverbial phrase, providing context for the main verb. While you are familiar with this concept, the formal trio of 以, 于, and 与 possess a wider and more abstract range of meanings than their colloquial equivalents. Understanding their core semantic domains is key.
1. 以 (yǐ): The Coverb of Instrumentality, Basis, and Purpose
The fundamental idea of 以 is the leveraging of one thing to achieve another. It answers "how?", "by what means?", or "on what basis?". Its functions are more abstract than the physically oriented 用 (yòng) (to use) or 拿 (ná) (to take).
  • Function A: Instrument or Method (replaces 用 yòng)
This is its most direct function, indicating the means by which an action is performed. It is preferred for abstract methods, strategies, or criteria.
  • 企业应以创新驱动发展。
Qǐyè yīng yǐ chuàngxīn qūdòng fāzhǎn.
(Enterprises should drive development by means of innovation.)
  • 他最终以微弱优势赢得了选举。
Tā zuìzhōng yǐ wēiruò yōushì yíngdéle xuǎnjǔ.
(He ultimately won the election by a slim margin.)
  • Function B: Basis or Rationale (replaces 根据 gēnjù)
以 introduces the standard, reason, or evidence upon which an action or judgment is based. The structure 以...为... (yǐ...wéi...) is extremely common here, meaning "to take... as...".
  • 法律以事实为依据，以法律为准绳。
Fǎlǜ yǐ shìshí wéi yījù, yǐ fǎlǜ wéi zhǔnshéng.
(The law takes facts as its basis and the law as its guiding principle.)
  • 我们不能以貌取人。
Wǒmen bùnéng yǐ mào qǔ rén.
(We cannot judge people by their appearance.)
2. 于 (yú): The Coverb of Spatiotemporal and Relational Location
于 is the formal counterpart to 在 (zài), but its domain extends to comparison (比 bǐ) and targets (对 duì). Its defining syntactic feature is its strong tendency to appear after the verb, a direct inheritance from Classical Chinese grammar. It places the verb's action within an abstract framework of time, place, or relation.
  • Function A: Time and Place (replaces 在 zài)
This is its primary formal use, almost always following verbs of occurrence, creation, or finalization.
  • 该会议将于下周在北京举行。
Gāi huìyì jiāng yú xiàzhōu zài Běijīng jǔxíng.
(The conference will be held in Beijing next week.) - Note that 于 handles time, while 在 can still be used for place in the same sentence.
  • 他出生于一个书香门第。
Tā chūshēng yú yīgè shūxiāng méndì.
(He was born into a scholarly family.)
  • Function B: Target or Relation (replaces 对 duì or 向 xiàng)
于 introduces the object or recipient of an abstract action, indicating directionality or relevance.
  • 此项规定适用于所有员工。
Cǐ xiàng guīdìng shìyòng yú suǒyǒu yuángōng.
(This regulation is applicable to all employees.)
  • 长期以来，他致力于基础科学研究。
Chángqī yǐlái, tā zhìlì yú jīchǔ kēxué yánjiū.
(For a long time, he has been dedicated to fundamental scientific research.)
  • Function C: Comparison (replaces 比 bǐ)
In statistical, financial, or technical writing, 于 is the standard for expressing comparison. Adjectives like 高 (gāo), 低 (dī), 大 (dà), 小 (xiǎo), and 多 (duō) are paired with it.
  • 今年的出口总额低于预期。
Jīnnián de chūkǒu zǒng'é dī yú yùqī.
(This year's total export value is lower than expected.)
  • Function D: The Agent in Passive Constructions (replaces 被 bèi)
This usage is highly literary. It indicates the agent or source of an action in a passive sense, often with verbs expressing suffering or limitation.
  • 他为名利所困，受制于人。
Tā wèi mínglì suǒ kùn, shòuzhì yú rén.
(He is trapped by fame and fortune, controlled by others.)
3. 与 (yǔ): The Coverb of Conjunction and Participation
与 serves as the formal equivalent of 和 (hé) (and) and 跟 (gēn) (with). Its core function is to link grammatically parallel elements, most often nouns or nominal phrases. It implies a more balanced, reciprocal, or formal relationship than its colloquial counterparts.
  • Function A: Conjunction (replaces 和 hé)
与 is the default choice for connecting nouns in titles, headings, and academic writing. It creates a symmetrical and polished tone.
  • 会议的主题是“传统与现代化”。
Huìyì de zhǔtí shì “chuántǒng yǔ xiàndàihuà”.
(The theme of the conference is "Tradition and Modernization.")
  • 这涉及经济、政治与文化等多个层面。
Zhè shèjí jīngjì, zhèngzhì yǔ wénhuà děng duō ge céngmiàn.
(This involves multiple levels, including economic, political, and cultural.)
  • Function B: Accompaniment or Participation (replaces 跟 gēn)
When meaning "with," 与 introduces another party involved in an action. It is standard in business and diplomatic contexts.
  • 我们希望与贵方建立长期稳定的合作关系。
Wǒmen xīwàng yǔ guì fāng jiànlì chángqī wěndìng de hézuò guānxì.
(We hope to establish a long-term and stable cooperative relationship with your side.)
  • 该结果与预期不符。
Gāi jiéguǒ yǔ yùqī bùfú.
(The result is not in accordance with expectations.)

Formation Pattern

1
The syntax of these coverbs is strict. 以 and 与 follow the standard S + Prepositional Phrase + V order, but 于 is the crucial exception.
2
Pattern 1: The 以 (yǐ) Structure
3
以 and its object (the means or basis) must precede the verb.
4
| Pattern Type | Formula | Example | Translation |

6
| Means/Method | S + 以 + Noun (Method) + Verb Phrase | 公司以数据分析来优化运营。 | The company uses data analysis to optimize operations. |
7
| Basis/Reason | S + 以 + Noun (Reason) + Verb Phrase | 法官以证据不足驳回了起诉。 | The judge rejected the prosecution on the grounds of insufficient evidence. |
8
| To take...as... | S + 以 + Noun A + 为 + Noun B (or Adj) | 企业应以诚信为本。 | Enterprises should take integrity as their foundation. |
9
Pattern 2: The 于 (yú) Structure
10
于 and its object (time, place, target) most often follow the verb.
11

12
|---|---|---|---|
13
| Place/Time | S + Verb + 于 + Noun (Place/Time) | 他毕业于2020年。 | He graduated in 2020. |

15
| Comparison | Noun A + Adj. + 于 + Noun B | 实际成本远高于预算。 | The actual cost is far higher than the budget. |
16
Pattern 3: The 与 (yǔ) Structure
17
与 can introduce a partner before a verb or link two nouns directly.
18
| Pattern Type | Formula | Example | Translation |
19
|---|---|---|---|
20
| Accompaniment | S + 与 + Noun (Partner) + Verb Phrase | 部长将与外宾举行会谈。 | The minister will hold talks with the foreign guests. |
21
| Conjunction | Noun Phrase A + 与 + Noun Phrase B | 本文探讨了技术与伦理的关系。 | This paper explores the relationship between technology and ethics. |

When To Use It

Using these coverbs correctly signals a high level of education and situational awareness. Their use is confined to formal contexts.
  • Academic and Scientific Writing: This is their primary domain. They are indispensable for describing methodology (以...方式), reporting results (高于/低于), and framing analysis (A与B的关系).
  • 本研究以深度访谈为主要研究方法，旨在探讨代际关系与价值观变迁的内在联系。 (This study uses in-depth interviews as its primary research method, aiming to explore the internal connection between intergenerational relations and value changes.)
  • Business, Legal, and Official Documents: Contracts, reports, formal emails, and official announcements use this language to convey authority and precision.
  • 合同附件与主合同具有同等法律效力。 (The contract addendum has the same legal force and effect as the main contract.)
  • 根据规定，此决议于公布之日起生效。 (According to regulations, this resolution takes effect from the date of its announcement.)
  • Formal Speeches and News Media: The language of government officials and news anchors is saturated with these terms for conciseness and gravitas.
  • 该大桥于昨日建成通车。 (The bridge was completed and opened to traffic yesterday.)
  • Professional Self-Introductions: Essential for resumes (简历) and cover letters (求职信).
  • 毕业于清华大学，以优异成绩获硕士学位。 (Graduated from Tsinghua University, obtaining a Master's degree with outstanding results.)
  • Idioms and Set Phrases (成语 chéngyǔ): These characters are fossilized within thousands of idioms, preserving their classical meanings.
  • 与世无争 (yǔ shì wú zhēng): to hold oneself aloof from the world.
  • 青出于蓝 (qīng chū yú lán): the student surpasses the master (lit. blue comes from indigo but is bluer).
  • 以偏概全 (yǐ piān gài quán): to generalize from a biased point of view.

Common Mistakes

Mastering these requires unlearning some deeply ingrained patterns from colloquial Chinese. Awareness of these common pitfalls is the first step to avoiding them.
  • Mistake 1: Placing 于 before the verb like 在.
This is the most frequent error, caused by direct translation of the 在 + Place + Verb pattern. The classical Verb + 于 word order must be memorized for key verbs.
  • Incorrect: *公司于2005年创立。
  • Correct: 公司创立于2005年。 (Gōngsī chuànglì yú 2005 nián.)
  • The Logic: In Classical Chinese, the verb was the core pivot, with locatives and temporals often following it. Modern formal Chinese retains this feature for 于, making it a key grammatical marker of high register.
  • Mistake 2: Using 以 as a standalone verb for "use".
以 is a coverb, not a main verb. It introduces the instrument for an action, but it isn't the action itself.
  • Incorrect: *请以您的护照。 (Intending to say "Please use your passport.")
  • Correct: 请以护照验证身份。 (Qǐng yǐ hùzhào yànzhèng shēnfèn. - Please verify your identity using your passport.)
  • The Logic: A sentence like 我以信用卡 is a fragment, meaning "I, by means of a credit card..." The listener is left waiting for the main verb (e.g., ...支付 - ...pay).
  • Mistake 3: Using 与 to connect verb phrases or clauses.
Unlike the more flexible 和, 与 is almost exclusively used to connect nouns or nominalized phrases. Connecting verbs with 与 sounds unnatural.
  • Incorrect: *他喜欢游泳与跑步。
  • Correct (Formal): 他喜爱游泳与跑步这两项运动。 (He likes the two sports of swimming and running.) - Here we add a noun 运动 to make the objects parallel.
  • Correct (Natural): 他喜欢游泳和跑步。
  • The Logic: 与 emphasizes a static, parallel relationship between two entities. Actions (verbs) are dynamic and are more naturally linked with 和 or simply listed in sequence.
  • Mistake 4: Register Mismatch — Using formal coverbs in casual contexts.
While grammatically correct, using these words when chatting with friends or ordering coffee is socially awkward. It creates an unnecessary and strange sense of distance.
  • Weird (to a friend): 我稍后与你联系。 (Wǒ shāohòu yǔ nǐ liánxì.)
  • Natural: 我待会儿跟你联系。 (Wǒ dāihuǐr gēn nǐ liánxì.)
  • The Analogy: This is akin to saying "I shall make contact with you at a subsequent time" instead of "I'll hit you up later." The tone does not match the situation.

Real Conversations

Authentic examples reveal how these coverbs function in their natural environments.

S

Scenario 1

From a University Professor's Email

```

李同学：

你好。关于你的论文选题，我认为可以更进一步，将A与B进行比较研究。建议以历史分析为切入点，相关文献列表已附于邮件末尾。请于下周三前提交一份开题报告。

祝好，

张教授

```

Analysis*: 将A与B进行比较研究 (conduct a comparative study of A and B) is standard academic phrasing. 以历史分析为切入点 (using historical analysis as a starting point) sets out the method. 附于邮件末尾 (is attached at the end of the email) and 请于下周三前提交 (please submit by next Wednesday) both demonstrate the Verb + 于 pattern for location and time.

S

Scenario 2

Excerpt from a Legal Contract

```

第五条：保密义务

乙方不得以任何形式向任何第三方泄露本协议内容及与项目相关的商业秘密。此义务不因本协议的终止而终止，其效力持续于协议终止后的五年内。

```

Analysis*: The language is extremely precise. 以任何形式 (by any means) is a classic legal catch-all. 与项目相关的商业秘密 (...business secrets related to the project) uses 与 to link the secrets to the project. 持续于... (continues in the five years after...) uses the post-verbal 于 to specify a duration.

Quick FAQ

Q: Can I just stick to 用, 在, and 和?

You can, but your productive ability will be capped at an intermediate level. You will be unable to produce sophisticated language required for professional or academic success in a Chinese-speaking environment. Furthermore, reading formal materials, from news to contracts, will be significantly more difficult without an intuitive grasp of 以, 于, and 与.

Q: How does 对于 (duìyú) relate to 于?

对于 is a compound preposition used to topicalize something, meaning "regarding" or "as for." It always appears at the beginning of a sentence or clause to set the topic. 对于这个问题，大家的看法不一。 (Regarding this issue, everyone has a different opinion.) While 于 can sometimes indicate a target (similar to 对), 对于's specific grammatical function is topicalization. You can't say *有助于对于我们.

Q: What is the difference between 与 and 及 (jí) for "and"?

Both are formal connectors. 与 connects items of equal rank and importance (A and B). 及 connects a secondary item or group to a primary one (A, and also B). Think of 及 as "as well as." Example: 会议讨论了公司的战略方向及其对财务的影响。 (The meeting discussed the company's strategic direction as well as its financial implications.) The strategic direction is the primary topic; the financial impact is secondary.

Q: I've seen 以为 (yǐwéi) meaning "to mistakenly think." Is that related to 以?

Yes, it is a fossilized word from the classical 以...为... structure. It literally meant "to take [A] to be [B]". Over time, it came to carry the implicit meaning that the assumption was wrong. So, 我以为他是老板 means "I thought he was the boss (but he isn't)." The classical structure is still visible.

Q: Is there a difference between using 以 and 拿 (ná)?

Yes, this distinction is crucial. 拿 is a physical action verb meaning "to hold, to take." It is used in spoken language for concrete objects: 他拿着一本书 (He's holding a book). 以 is an abstract coverb for means or method. You cannot 以 a concrete object in this way. You use an object by means of 以: 他以事实说服了我们 (He persuaded us with facts). You can't 拿事实 to persuade someone.
